The word "metaphysical" pertains to a branch of philosophy that deals with concepts that go beyond the physical or material world. It explores fundamental questions about existence, reality, and the nature of being. In a broader sense, it can refer to abstract concepts that cannot be easily defined or understood through empirical observation.
The term "metaphysical" comes from the Greek word "metaphysika," which translates to "that which is beyond the physical." The word "meta-" means "beyond," and "physika" is derived from "phusis," meaning "nature."
